My Umarex HK416A5 w/ suppressor, angled foregrip, PEQ-15, 5mm polycarbonate sight protector, Feyachi RDS-25, Vector Optics 5x flip-to-side Magnifier, PTS EPM Mag and genuine Magpul MOE Stock. Also using a Viper Tactical VX Sling. Got somerubber rail protectors, to make it more comfortable to hold. The internals were upgraded primarily for longevity, with a new inner barrel for a slight range boost. Here are my upgrades:
ORGA LEX05 6.05mm inner barrel – 275mm
Prometheus Air Seal Chamber Packing – Soft
Firefly Namazu Flat Hop – Hard
Air Pad v2/v3 3/16” 70D
I also cleaned up and shimmed the gearbox. Fair to say I'm happy with it!
